Hash Generator — MD5, SHA-1, SHA-256, SHA-512

MD5, SHA-1, SHA-256 & SHA-512 hashes — instant, in your browser.

Stays on your device. This tool runs in your browser — nothing you paste or open ever leaves it. Nothing uploaded, nothing to leak.

How to generate a hash

Type or paste your text and the MD5, SHA-1, SHA-256 and SHA-512 hashes are computed live in your browser. Copy any one with a tap. The SHA family uses the browser-native Web Crypto API; everything stays on your device.

A hash generator turns any text into a fixed-length fingerprint using MD5, SHA-1, SHA-256 or SHA-512. Paste your text and every hash is computed instantly in your browser — useful for checksums and integrity checks. Hashing is one-way and cannot be reversed.

What hashes are used for

Verifying a download has not been tampered with (checksums), comparing files without sharing them, deduplication, and storing fingerprints. For passwords, use a purpose-built password hash (bcrypt/argon2) on the server — raw MD5/SHA is not suitable for that.

FAQ

Is MD5 still secure to use?No, MD5 is cryptographically broken; practical collisions have been demonstrated since 2004 and RFC 6151 documents it as unsuitable for collision-resistant uses. It is fine only for non-adversarial checks like detecting accidental file changes; use SHA-256 when integrity matters.

What is the difference between hashing and encryption?Hashing is a one-way function with no key that cannot be reversed to recover the input, while encryption is reversible with the right key. Hashes are used to verify integrity or fingerprint data, not to hide and later restore it.

Why is SHA-256 preferred over SHA-1 or MD5?SHA-256 produces a 256-bit digest with no known practical collision attacks, whereas MD5 (128-bit) and SHA-1 are both broken; NIST has deprecated SHA-1 and a working collision was produced in 2017. SHA-256 is the modern default for checksums, signatures, and security-sensitive integrity checks.

Are the strings I hash sent anywhere?No. Hashes are computed in your browser using its built-in crypto, so the text or file you hash never leaves your device. You can fingerprint sensitive values without transmitting them.
